"How the hell does the iPhone differ from generation to generation?" some ask. "All the iPhones in recent years are all the same!" others exclaim.

It's true that most of the iPhone upgrades have been incremental, but in Apple's defense, why overhaul something that's already damn good? Innovation is exciting, but it also comes with risks. Sometimes, it's best to play it safe.

That being said, to prove that no iPhone is the same, here are the changes Apple has implemented for each line, from the iPhone 11 to the iPhone 15.

Announced in October, the iPhone 12 line was the first to introduce the new short-lived "mini" line. The iPhone 11's successor also brought 5G support. However, at the time, many critics shrugged at this because 5G wasn't widely available. Let's take a look at the series' new features.

iPhone 13

The iPhone 13 reportedly introduced 20% smaller notch, but in my personal opinion, I didn't like the change.

Sure, it was less wide, but it dipped even further into the display. On the plus side, this family of phones debuted a bigger battery, which means runtime on a single charge should have improved over the iPhone 12. But what else did the iPhone 13 bring to the table? Let's take a look.

Camera

• Cinematic Mode, a rack focus feature that changes the depth effect of your videos with bokeh

• Updated wide camera with brighter results in photos, videos

• "Sensor Shift" now available for entry-level phones (mini and standard iPhone)
